Abstract: A hypodermic injection system allows for the generation of a high pressure liquid jet capable of passing through the skin. The system uses two regions, the first region being flexible or squeezable and the second region having at least one exiting orifice through which the liquid jet can be expelled. The flexible region can be deformed by a pressure change in the surrounding container generated by an activatable gas generator that generates pressure within the first region that causes the liquid to be expelled.

Abstract: A dispensing device for viscous pastes, for multiple users, which deploys a plurality of color coded caps for their personal identification and use. The device is screwed onto a squeezable tube of paste (for example, toothpaste), and, as the tube is squeezed, the paste flows through the device, past caps in a “closed” position, and out of a desired number of caps in an “open” position, in order to dispense paste. The caps' conduits are of a predetermined circumference for dispensing the desired amount of the paste. A smaller circumference is more economical, as less paste would flow out of such a conduit. This would be especially useful when the users are children. Threaded or friction-fitting cap tops may be attached to the device. If attached by friction-fitting, the cap tops form orbital lips to ensure a tight frictional fit to the cap necks. Connecting bands link the dispensing cap tops to the device, so that the tops won't be lost.

In another embodiment, a door handle may be equipped with the marking mechanism, and the marking mechanism is triggered when the person uses the door handle. For some applications the marking mechanism may be releasably secured to an activating member.

Abstract: The tube has a non-metallized holographic decoration. This holographic decoration is an inner layer of the tube body which is of a laminate structure. The holographic film layer is a non-metallized layer to prevent the delamination of the tube body when the tube body is formed with an overlap seal. In an overlap seal an edge of the laminate film potentially will be in contact with the contents of the tube. A metallized holographic layer can react with the contents of the tube and cause a delamination of the film in the area of the seal and the consequent failure of the seal. The innermost layer of the tube body will be a layer that is bondable to an outermost barrier layer, and further that is bondable to the shoulder of the tube. It should be bondable to the innermost layer in order to form the longitudinal seal of the tube body. It should be bondable to the shoulder since the primary bond of the shoulder to the tube body is of the shoulder to the innermost layer of the tube body.

Abstract: Customized, Reusable Flow-Through Toothpaste Tube Attachment: a plastic or similar material (20) consisting of a threaded entrance orifice (23) which can be affixed to the threaded neck of a toothpaste tube (15) forming a seal. The threaded entrance orifice (23) is in communication with a continuous passage (30) which leads to an exit orifice (35). Once the attachment forms a seal with the threaded neck of a toothpaste tube (15), toothpaste can be forced through the passage (30) and out through an exit orifice (35) by squeezing the toothpaste tube. As toothpaste flows out of the exit orifice (35) of the attachment, it can be applied to the bristles of a toothbrush or the like. The reusable attachment (20) provides the flexibility to customize the exit orifice of a toothpaste tube as well as the angle at which toothpaste exits the tube.
